APOCELLUS.—TROGOPHL@US. 697 
Of this little species, with such remarkable male characters, we have received only 
one example from each locality: the male from the city of Guatemala has the hind 
body contracted, and as I have been unable to restore it to its natural length I cannot 
say if the structure of the terminal segments agrees exactly with that of the typical 
example from Chiriqui. 
8. Apocellus sordidus. (Tab. XVIII. fig. 15.) 
Parvus, minus gracilis, opacus, fusco-niger; elytris dilutioribus; antennis fuscescentibus, basi testacea ; 
pedibus flavis. 
Long. 23 millim. 
Hab. Guatemata, El Tumbador, Mirandilla, near the city of Guatemala, San Gero- 
nimo, Balheu (Champion). 
Antenne very stout; joints 4-10 short, the terminal joint more pallid than the 
preceding. Head small, quite dull, without definite sculpture. Thorax very small, 
strongly narrowed behind, dull like the head. Elytra rather longer than the thorax; 
very finely, densely, and minutely punctulate, not so dull as the head and thorax. 
Hind body broad, moderately shining. ‘Legs entirely pallid. In the male there is 
a slight lamination and deflection of the middle of the hind margin of the penultimate 
ventral plate, and the following segment is broadly deplanate along the middle. 
TROGOPHLCUS. 
Trogophleus, Mannerheim, Brach. p. 49 (1830); Erichson, Gen. et Spec. Staph. p. 801; Leconte, 
Tr. Am. Ent. Soc. vi. p. 242. 
This genus at present includes about one hundred described species ; it is very widely 
distributed, occurring even in oceanic islands. The genus is no doubt one of the most 
extensive of the Staphylinide, but its species have been as yet but little collected and 
studied; Leconte records about fifty species known to him as occurring in America 
north of Mexico, but the greater portion still remain undescribed. <A comparatively 
small number of species, represented only by very few examples, have yet been obtained 
in our region, and I have little doubt that Central America harbours many others in 
addition to those recorded here.
